Sarah, yes the flowers on this one are about half the size of my standard Phals. The plant is plenty big though!
It appears to have a branching habit so what it lacks in size it could make up for in numbers of flowers. It definitely has potential. I hate the way the grower I bought this one from staked it. It's a double spiker and they staked the spikes away from each other in the shape of a V, and rather than let the flowers form a nice natural arch they are clipped all the way to the tip of the spike. Looks like it spent several months in a torture chamber!
That will be remedied very soon.
